Three years ago I wrote a post entitled "Leadership Is An Innate Skill?". In that post, I essentially avoided the core topic (because I didn't have an opinion), but I made some anecdotal points about how one could foster one's leadership style (which I thought was a more important point). My views on leadership haven't changed fundamentally since my original post in that I believe that some leadership skills can be learned, there are many different leadership styles, and contextual and organizational items play a role (e.g., can influence one to diverge from one's own leadership style or enhance it).
That said, reader Tom Hartly has brought to my attention a new book entitled, "Leadership Is Innate". I've not read the book, but one can peruse a bit online and figure out which side of the coin is being argued. The description reads:
Top CEOs will tell you that leadership traits come as "part of the package" and "can't really be taught". Scientists have recently begun to discover how genetic differences contribute to key leadership skills.
